OP did you just have sex with my husband?!!!! 
Okay I can relate to this, truly.
My ex when we first got together had a wank in front of me and I was a bit
sweet naive ingenue that I was. But then I was 'Okay, fair play to him.
He's not embarrassed about masturbating nor does he deny he does!' (first bf never masturbated. Allegedly. 
So I had no real issue with that tbh. Likewise getting to know someone, first time with that person etc can be awkward - what the real shame her is that he didn't verify whether you had come or not and whether you would like to come or not via mutual masturbation, finishing yourself off or him offering a helping hand or mouth.
But if you didn't say anything either because of awkwardness or embarrassment then maybe he thought you had or as you weren't asking that you weren't bothered. This would rankle.
As for the ball stroking my other half adores this and has been quite happy with this and an open wank when I have been unable to make love due to post birth trauma or indeed when I am knackered and also when I have come and he hasn't and I was giving him a Hurry up love expression the timing has sometimes been off and he didn't want me to have to keep at it if I'd already orgasmed which is actually quite considerate when you think about it.
But we have known each other for years.
In short
I would be fine with him having a wank
I would not be unduly concerned about him not having come
I would be unsurprised he likes having his balls stroked
I would be happy he was confident enough to express what he wanted
But
I would be a bit
about the beer
I would be a lot
about him not asking what I wanted/whether I wanted anything
If you like the guy you need to talk this through, get over your own shyness and say what you want.
As for him being hirsute that is something you can either get used to or not.
If not it probably ends now.
As for him wanking = porn obsession, no I don't buy that. Yes, he probably has a 'wank bank' of images, a lot of men do, in the same way many women have a fantasy that works time and again.
but he wasn't excluding you nor not making an effort prior (3 positions. 3?!!
Her on top. Doggy. And normal.
Tis a Garth merenghi reference if you were wondering.
So either he is worth the effort of a post coitus post mortem...or he's not.
Communication is what is needed here.
Good luck!
